I have wanted to build a CP5 for years and it did not disappoint. The instructions are best-in-class and the results, especially for voice over, are really great. What a great clean, but not sterile, sound and with the Op Amp Colour board inside, I can get a range of tones from the CP5 that I can't get from my other preamps. The whole build took about an hour and a half and I captured it all for a YouTube video in case that can be helpful for someone else either considering purchasing or building their own CP5. I am a huge fan of DIYRE and Peterson really knocked it out of the park with this one.
